What is the Principle of Textile Waterproofing Agent

Aug 10, 2021

Textile waterproofing agent is used for the functional finishing of textile fabrics. It has a wide range of applications, involving various fields of textiles, and there are many types of products. The same product can be used for different fabrics, and different products can give fabrics different properties. .
What is the principle of textile waterproofing agent

According to its performance, textile waterproofing agents can be divided into four aspects: waterproof, oil-proof, anti-fouling and easy to decontaminate. After finishing with different textile waterproofing agents, the above four properties can be given to textiles.The so-called waterproof refers to the formation of water droplets instead of immediately penetrating the cloth surface while reducing the absorption power of the fabric to water. The waterproof finishing fabric will still penetrate when the water stays for a long time, but it has better breathability and comfort than the waterproof finishing.

The waterproof finishing clothes can prevent the fabrics from being permeable when exposed to water. When daily clothing is not waterproofed, it will get wet almost immediately when encountering rain. The waterproof finishing textile fabrics can give the fabric moisture and permeation in a short time. The effect is that it can temporarily avoid the wetting of the textile fabric when it encounters a small amount of water for a short period of time; wipe off the water droplets on the textile fabric within a certain period of time, and it is still possible to keep the fabric dry.

The principle of anti-oil and anti-fouling is the same as the principle of waterproofing. They all change the composition of the fiber surface layer and firmly adhere to the fiber or combine with the chemical fiber to prevent the fabric from being wetted by common oil stains.Water- and oil-proof fabric is a functional and intelligent fabric. The waterproof and oil-repellent textiles can resist rain and oil stains, and can discharge the sweat and perspiration of the human body in time, so as to keep the human body dry and warm. It is a waterproof and oil-proof meal used in decoration and industrial fields. Tablecloths, car protective covers, etc. are also popular.
Easy decontamination finishing means that textiles and other fibers are particularly easy to stain, and they are not easy to clean after being contaminated. The textiles finished with Deco Nano Easy Decontamination Finishing Agent can obtain easy wiping performance.

With Deco nano three anti-stain finishing agent or easy stain removal finishing agent, the surface tension of the fabric can be lower than the surface tension of water, oil and stains, and it can give textiles anti-fouling and easy stain removal performance.
Types of fabric waterproofing agent:
The working principle of fabric waterproofing agent:

Fabrics of different fibers have different hydrophilic properties. If it is treated with a fabric waterproofing agent, that is, the hydrophobic substance is absorbed or deposited on the fiber, so that the surface performance of the fabric is changed, and it is not easy to be wetted by water. It is wet and soft to the touch.
1. Fluorine-containing water-repellent agent: Fluorine-containing compound is currently the most widely used fabric water-repellent agent, emulsion type, easy to use, and the treated fabric feels soft and has durability.
2. Fluorine-free water repellent: it does not contain fluorocarbons and is environmentally friendly. Its excellent waterproof performance and wide applicability are praised by many European and American brands, and it is increasingly accepted by the market.
